Oracle's Cache Fusion cluster database architecture is a new shared cache architecture that overcomes the limitations of traditional shared nothing and shared disk approaches to provide highly scalable and available database systems for SAP customers.
Customer needs are:
- The database server must be highly available; SAP users should enjoy uninterrupted server access regardless of hardware and/or software failures. Without RAC, the database server is still a single point of failure.
- The server must be flexible when adding processing power as dictated by business growth; customers want to enlarge their systems incrementally. They cannot afford to invest in large servers that may be idle for long periods. Therefore customers want a scalable solution to get the best possible return-on-investment.
- The server must be adaptable to changing workloads; the database must provide seamless support for changing workload requirements as mandated by rapidly evolving business needs.
Real Application Clusters with its Cache Fusion cluster database architecture helps customers meet these demanding and evolving business needs.
